I currently take Adderall xr 30mg and Wellbutrin xl 150mg. Just recently my fiance and I began working out. We lift (free weights) 4 days a wk and I try to do at least 30min. of cardio on the elliptical 5 days a week. My problem is that I cannot seem to get my heart rate up. I can sweat through a sweatshirt, be breathing 50 times a minute, and pushing w/everything I have, and my HR is still staying around 140. This is with my cardio. My fiance thinks I might not be working hard enough. I however, know that I am pushing w/everything I have. Are next step is trying to find out if the meds may have something to do with it. I have lost a total of 50lbs since being diagnosed, back in September of 2005. I just need to figure out what I can do to get my HR up. My target HR is around 160. If anyone could help I would be forever greatful!!:confused:
